This is a transversal. A transversal is a line, ray, or line segment that intersects two or more coplanar lines, rays or line segments, each at a different point. As you can see, this transversal includes two parallel lines. These lines do not always have to be parallel.
This is another example of a transversal. This example has numbers to demonstrate which angles have special names. Here are the angle pairs. Each of the angles in an angle pair are congruent.
Angles 3 and 6, and 4 and 5 are Alternate Interior Angles. These angles are on opposite sides but are still on the inside of the lines.
Angles 1 and 8, and2 and 7 are Alternate Exterior Angles. These angles are on opposite sides but are still on the outside.
Angles 2 and 6, 4 and 8, 1 and 5, and 3 and 7 are Corresponding Angles. The angles are congruent.
4. Angles 3 and 5, and 4 and 6 are Same Side Interior angles. These angles add up to 180 degrees.
